RELATED APPLICATIONS

This application claims the benefit, under 35 U.S.C. §119, of U.S. Provisional Patent Application Ser. No. 61/893,021 filed on Oct. 18, 2013, and entitled “Decorative Fragrance Dispensing System,” which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

This disclosure generally relates to a decorative fragrance dispensing system.

BACKGROUND

Fragrance dispensing products may be used to dispense fragrance into surrounding air (for example, within a room, office, workplace, or household), thereby “freshening” the air and creating a pleasant atmosphere. In creating the pleasant atmosphere, ambient lighting may also be included as part of a fragrance dispensing product. Examples of types of fragrance dispensing products may include candles, air fresheners, electric fragrance dispensers, etc.

Some fragrance dispensing products use fragrance elements such as melted wax, gels, and/or liquids, to hold and dispense fragrance. These products may become messy if the wax, gels, or liquids are spilled. Further, children and/or animals may be inclined to play with or eat the wax, gels, or liquids. Hence, current fragrance dispensing systems may present a danger to children and/or animals.

Some products may use molded EVA plastic infused with fragrance instead of wax, gels, or liquids. However, such products use heating elements to heat the EVA plastic to temperatures between about 100° F. and 150° F. The heat causes the EVA plastic to release the fragrance. Using a heating element within a fragrance dispensing system may be dangerous to people or articles that may come in contact with the heating element or a heated portion of the fragrance dispensing system. Further, using molded plastics may not enable sufficient airflow to pass through the fragrance dispensing system to infuse the air with the fragrance.

SUMMARY

Disclosed is a fragrance packet that may be filled with ethylene vinyl acetate (EVA) beads that are infused with fragrances. The disclosed fragrance packet may resolve or mitigate at least one disadvantage of current systems described above and or one or more additional disadvantages known in the relevant art. The fragrance packet may have a high fragrance load (e.g., 17%). Throughout the process of infusing the fragrance into the EVA beads and during use of the fragrance packet, no additional heat (e.g., above room temperature) may be applied to the EVA beads, which may enable the EVA beads to last longer and to maintain a high level of fragrance for distribution in multiple applications and settings. The fragrance packet may be used passively (e.g., as a standalone apparatus) or actively (e.g., with a fragrance dispensing system that includes a fan). Hence, the fragrance packet may be portable.

In an embodiment, a bead packet apparatus includes a plurality of beads that have been infused with fragrance. The apparatus further includes a fabric casing enclosing the plurality of beads.

In an embodiment, the plurality of beads include ethylene vinyl acetate (EVA) beads. The plurality of beads may be configured to release the fragrance over a period of time in the absence of heat above room temperature. The fragrance may be released in response to receiving an air flow between the plurality of beads. The fabric casing may include a mesh that enables the airflow through the plurality of EVA beads. A total surface area of the plurality of EVA beads may be large enough to release a human detectable amount of fragrance in the absence of heat above room temperature. A fragrance load of the EVA beads may be at least 17%.

In an embodiment, the apparatus further includes a hook configured to attach to the fabric casing. Alternatively, a size and shape of the bead packet may fit a platform of a fragrance dispensing apparatus. The fragrance dispensing apparatus may be configured to receive the bead packet at the platform. The fragrance dispensing apparatus may further be configured to actuate air flow through the bead packet, the bead packet remaining substantially unheated by a scent dispensing apparatus during actuation of the airflow.

In an embodiment, a method includes receiving an air flow between a plurality of beads enclosed by a fabric casing. The method further includes releasing a fragrance from the plurality of beads in response to the air flow in the absence of heat above room temperature.

In an embodiment, the plurality of beads include ethylene vinyl acetate (EVA) beads. Releasing the fragrance may occur over a period of time. Releasing the fragrance may include releasing a human detectable amount of fragrance in the absence of heat above room temperature. In an embodiment, the air flow is generated by a fan of a fragrance dispensing apparatus.

In an embodiment, a method of forming a bead packet apparatus includes tumbling a plurality of beads with one or more fragrance agents. The method further includes encasing a portion of the plurality of beads into a fabric casing.

In an embodiment, tumbling the plurality of beads is performed in a sealed tumbling machine. Tumbling the plurality of beads may be performed without heating the plurality of beads above room temperature. Further, tumbling the plurality of beads may be performed for at least one hour. Alternatively, tumbling the plurality of beads may be performed for at least three days. Tumbling the plurality of beads may be performed until a fragrance load of the beads is at least 17%.

DETAILED DESCRIPTION

Referring to FIG. 1, an embodiment of a fragrance dispensing system is depicted and generally designated 100. The fragrance dispensing system 100 may include a housing 110, an ethylene vinyl acetate (EVA) bead packet 120, a lower module 130, and a fan 140. In some embodiments, the fragrance dispensing system 100 may also include a topper 170.

The housing 110 may include a platform 112 and a sidewall 116 coupled together such that the platform 112 and the sidewall 116 define a cavity that includes an upper portion 151 and a lower portion 152. Further, the platform 112 may include one or more openings, such as the opening 114 defined therein. The opening 114 may communicatively couple a space 150 above the platform 110 to the upper portion 151 of the cavity. For example, a change of air pressure within the upper portion of the cavity 151 may cause an airflow path to pass between the space 150 and the upper portion 151 of the cavity via the openings including the opening 114. Likewise, the sidewall 116 may include one or more openings, such as the opening 118 defined therein. The opening 118 may communicatively couple a space 153 adjacent to the sidewall 116 to the upper portion 151 of the cavity. The housing 110 may be formed from and include materials such as ceramic materials, poly resin materials, wax materials, etc. For example, the housing 110 may include ceramic, glass, poly resin, plastic, wood, metal, composites, another type of shapeable material, or a combination thereof.

The platform 112 may be configured to receive the EVA bead packet 120. For example, a size and/or a shape of the platform 112 may retain the EVA bead packet 120 when placed in contact with the EVA bead packet 120.

The EVA bead packet 120 may include a plurality of EVA beads such as the EVA bead 122 and a casing 124 enclosing the plurality of EVA beads. An embodiment of the EVA bead packet 120 is described further with reference to FIG. 12.

The lower module 130 may include a battery 131, a locking mechanism 132, a recharging cable 133, at least one light emitting diode (LED) 134, a switch connector 135, a turnable knob 136, a translucent plastic plate 137, and a controller circuit 138. Although not depicted in FIG. 1, the lower module 130 may include additional wires and circuitry coupling the elements of the lower module 130 together to enable various operations of the lower module 130 as described herein. The lower module 130 may be coupled to a fan 140 by a motor 160 to enable the motor and fan as described herein.

The battery 131 may include any battery capable of powering the motor 160 and the at least one LED 134. For example, the battery 131 may be a rechargeable high capacity lithium ion battery, such as a low voltage and power consumption DC 3.7 volt rechargeable lithium ion battery. The battery 131 may be electrically coupled to the motor 160 and the at least one LED 134 via the controller circuit 138 as described further with reference to FIG. 2. In an embodiment, the battery 131 may be capable of operating the fragrance dispensing system 100 as described herein for a period of at least 80 hours. In one or more other embodiments, the battery 131 may be a lower capacity battery and may be capable of operating the fragrance dispensing system 100 as described herein for a period of less than 80 hours.

The locking mechanism 132 may include any type of locking mechanism capable of coupling the housing 110 to the lower module 130 when enabled and releasing the housing 110 from the lower module 130 when disabled. In an embodiment, the locking mechanism 132 includes a twist locking mechanism. For example, the locking mechanism 132 may include a notch attached to a side of the lower module 130 as depicted in FIG. 1. The notch may be received by the housing 110. A particular embodiment of the locking mechanism is described further with reference to FIGS. 6A-7.

The recharging cable 133 may include any type of recharging cable capable of charging the battery 131. In an embodiment, the recharging cable 133 is electrically coupled to the battery 131 via the controller circuit 138 as described with reference to FIG. 2. The recharging cable 133 may further be configured to couple to an electrical outlet (e.g., a wall outlet) to receive power for recharging the battery 131. In an embodiment, the recharging cable 133 is a 1 amp 5 volt rechargeable cable.

The at least one LED 134 may be configured to produce light within the upper portion 151 and the lower portion 152 of the cavity. The light may pass through the translucent plate 137. The light may further pass through the opening 114, the opening 118, or both, thereby producing ambient lighting around the fragrance dispensing system 100. In an embodiment, the at least one LED 134 includes six LEDs coupled to the controller circuit 138.

The switch connector 135 may be configured to receive the turnable knob 136 and to place the turnable knob in communication with a switch of the controller circuit 138. For example, the switch connector 135 may be keyed with a star shape that enables an inside of the turnable knob 136 to be press fit to the switch connector 135 and locked into place. The turnable knob 136 may then be rotated to activate different settings of the switch connector 135 and an associated switch coupled to the controller circuit 138.

The translucent plastic plate 137 may cover the at least one LED 134 thereby separating the at least one LED 134 from the lower portion 152 of the cavity. In an embodiment, the translucent plastic plate 137 is cloudy white to modify light from the at least one LED 134 to generate an ambient lighting. Other types of plates are also possible, such as a transparent plate.

The controller circuit 138 may include one or more inputs, switches, processors, and/or circuits capable of initiating operations associated with the fragrance dispensing system 100. An embodiment of the controller circuit 138 is further described with reference to FIG. 2.

The fan 140 may include any type of ventilator system capable of generating an airflow path from the space 150 above the platform to the lower portion 152 of the cavity via the opening 114 of the platform 112 and via the upper portion 151 of the cavity. The airflow path may further pass from the lower portion 152 of the cavity to the space 153 adjacent to the sidewall 116 via the upper portion 151 of the cavity and via the opening 118 of the sidewall 116. To generate the airflow, the fan 140 may use a reverse motion. For example, the fan 140 may be configured to pull air down through the cavity (e.g., from the upper portion 151 to the lower portion 152). In an embodiment, the fan 140 includes two diametrically opposed blades 142, 144. An angle and size of the blades 142, 143 may reduce a noise emitted by the fan while increasing an airflow through the airflow path. In an embodiment, the fan includes three blades. The fan 140 may also be transparent. For example, the fan 140 may be formed of colorless see-through plastic such that light from the LED 134 may pass through the fan 140.

The motor 160 may include any type of motor capable of driving the fan 140. The motor 160 may further include cloth brushing 162. The cloth brushing 162 may reduce an amount of noise and/or vibration associated with operation of the motor 160.

The topper 170 may be configured to fit with the housing 110. When coupled together, the topper 170 and the platform 112 may define an upper cavity configured to retain the EVA bead packet. The topper 170 may include at least one opening 172 defined therein. The at least one opening 172 may enable an air flow path to pass through the EVA bead packet 120 and the at least one opening 114 without being restricted.

During operation, the controller circuit 138 may receive one or more signals indicating an operating state of the fragrance dispensing system 100. Particular embodiments of the operating states of the fragrance dispensing system 100 are described further with reference to FIG. 2. Based on the operating state, the controller circuit 138 may provide electrical power to the motor 160 from the battery 131. The motor 160 may convert the electrical power to mechanical power to drive the fan 140. The fan 140 may cause air to flow in a particular airflow path. For example, the fan 140 may draw airflow in a direction away from the EVA bead packet 120, thereby drawing air from the space 150 above the platform 110 through the EVA bead packet 120 and through the at least one opening 112 into the upper portion 151 of the cavity. An embodiment of the airflow path is further described with reference to FIG. 3. Depending on the operating state, the controller circuit 138 may further provide electrical power to the at least one LED 134.

As further operations, a user may be able to disable the locking mechanism 132 enabling the housing 110 to be separated from the lower module 130. The housing may be replaced by a second housing. For example, the user may prefer a style of the second housing as compared to the housing 110. The second housing may include a second platform configured to receive the EVA bead packet 120. In an embodiment, a plurality of interchangeable housings with different designs may be used with lower module 130.

A benefit associated with the fragrance dispensing system 100 is that the combination of the extended surface area of the EVA beads with the airflow path produced by the fan 140 may enable the fragrance dispensing apparatus to dispense fragrance without heating the EVA beads 122 in contrast to systems that use molded EVA plastic and/or traditional airflow paths. Other advantages and benefits of the fragrance dispensing system 100 will be apparent to persons of ordinary skill in the relevant art having the benefit of this disclosure.

Referring to FIG. 2, a block diagram of an embodiment of a system for fragrance dispensing is depicted and generally designated 200. The system 200 may include a controller circuit 210, a four wire switch 220, a power save switch 222, a battery charge input 224, a fan motor 230, at least one LED 232, and a battery 240. The controller circuit 210 may correspond to the controller circuit 138 of FIG. 1, the four wire switch 220 may correspond to and be coupled to the switch connector 135, and the battery charge input 224 may be configured to couple to the recharging cable 133. Further, the fan motor 230 may correspond to the motor 160 and the at least one LED 232 may correspond to the at least one LED 134.

The controller circuit 210 may include one or more integrated circuits 212, a DC battery controller 214, a recharge controller 216, and a motor controller 218. Although, the integrated circuits 212, the DC battery controller 214, the recharge controller 216, and the motor controller 218 are depicted as distinct, in other embodiments, one or more of the integrated circuits 212, the DC battery controller 214, the recharge controller 216, and the motor controller 218, or portions thereof, may be combined.

In an embodiment, the controller circuit 210 includes a printed circuit board (PCB). The PCB may be coupled to the four wire switch 220, the power save switch 222, and the battery charge input 224. The PCB may be further coupled to the integrated circuits 212, the DC battery controller 214, the recharge controller 216, and the motor controller 218. The PCB may also be coupled to the fan 230 and the at least one LED 232.

The integrated circuits 212 may include a processor capable of performing operations associated with the system 200 as described herein. For example, the processor may include any type of processing device such as a central processing unit (CPU), a digital signal processor (DSP), a peripheral interface controller (PIC), and/or another type of processing element.

The DC battery controller 214 may perform operations to selectively operate the battery 240. For example, the DC battery controller 214 may disconnect an output of the battery 240 in response to a determination that the battery has reached a predetermined level of discharge. Further, the DC battery controller 214 may reduce an amount of current drawn from the battery 240 in response to determining that the amount of current exceeds a predetermined threshold. Additionally, the DC battery controller may disconnect an output of the battery 240 in response to an input received from the four wire switch, 220, the power save switch 222, the battery charge input 224, or a combination thereof.

The recharge controller 216 may receive a charging current from the battery charge input 224. Based on the charging current, the recharge controller 216 may generate a charging input usable to charge the battery 240. The charging input may be directed by the recharge controller 216 into the battery 240. Upon detecting that the battery 240 is charged beyond a threshold, the recharge controller 216 may disconnect the charging input from the battery 240.

The motor controller 218 may selectively control the fan motor 230 to adjust a speed of the fan motor 230. For example, the motor controller 218 may receive a signal from the integrated circuits 212 indicating that a speed of the fan motor 230 should be increased or decreased. Based on the signal, the motor controller 218 may increase an amount of power supplied to the fan motor 230.

During operation, the controller circuit 210 may selectively enter an off state, a light state, a low state, or a high state. For example, a user may position the four wire switch 220 to one of four positions corresponding to a particular state. The particular state may be communicated to the integrated circuits 212. The controller circuit 210 may refrain from operating both the fan motor 230 and the one or more LEDs 232 while in the off state. The controller circuit 210 may further refrain from operating the fan motor 230 and may operate the one or more LEDs 232 while in the light only state. The controller circuit 210 may also operate the fan motor 230 at a low speed while in the low state. The controller circuit 210 may operate the fan motor 230 at a high speed while in the high state. Both the high state and the low state may correspond to and be included as part of an on state of the system 200.

The system 200 may further selectively enter a power saving state. For example, a user may position the power save switch 222 to one of two positions indicating to the integrated circuits 212 whether the system 200 is to enter the power saving state. While in the power saving state, the controller circuit 210 may perform power saving operations for a first period of time and may be powered off for a second period of time. To illustrate, the controller circuit 210 may perform power saving operations during 4 hours of a 24 hour period. The power saving operations may include operating the fan for a first duration (e.g., for a 15 minute period) and ceasing to operate the fan for a second duration (e.g., for a 5 minute period). Thus, during the power saving state, the system 200 may conserve power, thereby prolonging an amount of time between battery charges.

A benefit associated with the system 200 including the power save switch 222 is that the system 200 may be more portable as compared to fragrance dispensing systems that do not have power save options. For example, the system 200 may be operated independent of a power input for longer than other systems. In an embodiment, the battery 240 may be able to operate the system 200 for more than 80 hours without being recharged. Other advantages and benefits of the system 200 will be apparent to persons of ordinary skill in the relevant art having the benefit of this disclosure.

Referring to FIG. 3, a diagram of an embodiment of an air flow path of an embodiment of the system 100 for fragrance dispensing is depicted. In following the air flow path, air may move from the space 150 above the platform 112 to the upper portion 151 of the cavity via the at least one platform opening 114. In passing through the platform 112, the air flow may further pass through the EVA bead packet 120. In passing through the EVA bead packet 120, the air flow may absorb fragrance from the EVA bead packet 120. The scented air may then flow from the upper portion 151 of the cavity to the lower portion 152 of the cavity due to suction created by the fan 140. The scented air may be compressed in the lower portion 152 of the cavity such that the scented air is forced upward along the sidewall 116 of the housing 110. Hence, the air flow path may pass upward from the lower portion 152 of the cavity to the upper portion 151 of the cavity. From there, the air flow path may pass from the upper portion 151 of the cavity to the space 153 adjacent to the sidewall 116 via the at least one sidewall opening 118. Hence, the system 100 may pull air downward through the EVA bead packet 120 and subsequently force the air outward from the housing 110. Although, FIG. 3 is described in terms of having at least one platform opening 114 and at least one sidewall opening 118, the at least one platform opening 114 may include multiple openings to increase an air flow into the housing 110 and the at least one sidewall opening 118 may include multiple openings to increase an air flow out of the housing 110.

A benefit of the air flow pattern described with reference to FIG. 3 is that an amount of air passing through the EVA bead packet 120 and subsequently passing though the at least one sidewall opening 118 may be greater as compared to systems that do not pull air downward into the lower portion 152 of the cavity. For example, alternate systems may experience less air being directed through the EVA bead packet 120 due to a lack of control over the air flow path. Hence, the system 100 may better disperse fragrance from the EVA bead packet 120 as compared to systems that do not pull air downward and subsequently force the air outward. Other advantages and benefits of the air flow path of the system 100 will be apparent to persons of ordinary skill in the relevant art having the benefit of this disclosure.

Referring to FIGS. 4A-4C, an embodiment of the fragrance dispensing system 100 is depicted from multiple views. Although FIGS. 4A-4C depict the fragrance dispensing system 100 as including a weaved pattern defining the at least one platform opening 114 and the at least one sidewall opening 118, other embodiments of the fragrance dispensing system 100 may include other designs.

Referring to FIG. 4A, an embodiment of the fragrance dispensing system 100 including the topper 170 is depicted from a top angled view. The topper 170 may include at least one opening 172 defined therein. In an embodiment, the topper 170 includes a plurality of openings defined therein. The collective area of the openings may be greater than or equal to the collective area of platform openings (e.g. the platform opening 114) defined in the platform 112. By having an area that is greater than or equal to the area of the platform openings, the topper 170 may refrain from causing additional air flow resistance to the platform 112. Hence, air may flow freely through the topper 170.

The topper 170 may be coupled to the housing 110 via a press fit mechanism. In other embodiments, other mechanisms may be used to secure the topper 170 to the housing 110. When coupled to the housing 110, the topper 170 and the platform 112 may define a cavity that is configured to retain the EVA bead packet 120.

A benefit of the topper 170 is that the EVA bead packet 120 may be retained securely in place, thereby preventing the EVA bead packet from falling or becoming lost should the fragrance dispensing system be moved or jostled. Other benefits and advantages of the topper 170 will be apparent to persons of ordinary skill in the relevant art having the benefit of this disclosure.

Referring to FIG. 4B, an embodiment of the fragrance dispensing system 100 with the topper 172 removed is depicted from a top angled view. The platform 112 may be concave shaped to better retain the EVA bead packet 120. As depicted in FIG. 4B a plurality of platform openings (e.g., including the platform opening 114) may be defined in the platform 112. Having multiple platform openings may enable the system 100 to have better air flow through the platform 112, and thereby through the EVA bead packet 120, as compared to systems that have relatively few openings. Other benefits and advantages of the platform 112 with platform openings defined therein will be apparent to persons of ordinary skill in the art having the benefit of this disclosure.

Referring to FIG. 4C, an embodiment of the fragrance dispensing system 100 that includes the EVA bead packet 120 is depicted from a side view. The EVA bead packet 120 may be sized to fit over the platform openings 114. When the system 100 is activated (e.g., by the turnable knob 136), fragrance may be drawn from the EVA bead packet 120 downward into the housing 110. The fragrance may then be pushed out through a plurality of sidewall openings (e.g., including the sidewall opening 118) in order to disperse the fragrance through a room. A cumulative area of the sidewall openings may be greater than or equal to a cumulative area of the platform openings, thereby preventing restriction of air flow through the fragrance dispersing system 100. Other benefits and advantages of the sidewall 116 with sidewall openings defined therein will be apparent to persons of ordinary skill in the art having the benefit of this disclosure.

Referring to FIG. 5, an exploded view of an embodiment of a lower module is depicted and generally designated 530. The lower module 530 may correspond to the lower module 130. For example, the lower module 530 may include the battery 131, the locking mechanism 132, the at least one LED 134, the translucent plastic plate 137, the controller circuit 138, the fan 140, and the motor 160. The lower module 530 may also include an o ring 590, a motor mount 539, and a motor cover 564.

The o ring 590 may help secure a housing (e.g., the housing 110) coupled to the lower module 530. The o ring 590 may further seal the housing (e.g., the housing 110) to the lower module 530, thereby protecting the air flow pattern described with reference to FIG. 3 by preventing air seepage. In an embodiment, the o ring may be a 3 mm thick rubber gasket. The motor mount 539 may be configured to receive and retain the motor 160. The motor mount 539 may further be shaped to substantially retain the battery 131 as well, thereby reducing vibration and noise associated with the lower module 530. The motor cover 564 may include a plastic white motor cover. A non-transparent finish may help modify lighting received by the at least one LED 134 to create ambient lighting. In an embodiment, the motor cover 564 is coupled to the motor mount 539 by screws on either side of the motor cover 564. Other benefits and advantages of the o ring 590, the motor mount 539, and the motor cover 564 will be apparent to persons of ordinary skill in the relevant art having the benefit of this disclosure.

Referring to FIG. 6A, an embodiment of a lower module 630 including a first embodiment of a locking mechanism is depicted. The lower module 630 may correspond to the lower module 130. The lower module 630 may include a switch 608. The switch 608 may correspond to the power save switch 222 of FIG. 2. The lower module 630 may also include screw holes 604, 606. The screw holes 604 may enable the lower module 630 to couple to the translucent plate 137 and the screw holes 606 may enable the lower module 630 to couple to the motor mount 539.

The lower module 630 may further include molded letters 602. The molded letters 602 may provide instructions to a user for activating the locking mechanism 132.
